FEATURES
RCBS Cowboy Dies match tough steel to the tough jobs. The die bodies are
machined and hardened until they’re tough enough to meet our standards, yet
smooth enough to handle the most delicate brass case.
Sizer dies are vented to avoid case damage and are made to absolutely precise
tolerances. And there’s extra muscle where it counts, in the headed decapping
pin. Expander decapping units are designed so the decapping pin can be
replaced, if necessary. Seater dies have a unique design which aligns the bullet
with the case mouth an instant before seating.
Interior polishing helps brass work smoothly with
very little friction and cannot chip or peel with age.
All RCBS Cowboy Dies feature a solid brass lock
ring that allows tight control over precise adjust-
ments. RCBS dies are manufactured with the stan-
dard 7/8”-14 thread and are designed for use with a
shell holder having a lip thickness of 0.125”. Any
variations of these dimensions may cause headspace
or insufficient sizing problems.
GENERAL INFORMATION
Reloading rifle or pistol ammunition with lead (non-jacketed) bullets requires a
3-Die Set. The first die sizes and decaps the case. The second die expands the
case neck to the correct diameter to securely hold the lead bullet and flare the
case mouth to avoid shaving lead off the bullet. The third die seats and crimps
the bullet
PACKAGING

convenient and attractive traditional

RCBS to protect your dies in shipment

holds the dies firmly in place to prevent
damage and rolling around. Each box

inside lid for quick reference. The die
